PIB TrackerFoundation laid for fifth-generation fighter's test centre
Andhra's Puttaparthi will host the AMCA Core Integration & Flight Testing Centre, the spine of India's stealth-fighter ambition, alongside a cluster of naval and ammunition plants.
What happened
- On 15 May 2026, the Defence Minister and the Andhra Pradesh Chief Minister jointly laid foundation stones for a set of aerospace and defence projects at Puttaparthi, Sri Satya Sai district, Andhra Pradesh.
- The headline project is the Core Integration & Flight Testing Centre at Puttaparthi, built to fast-track the fifth-generation Advanced Medium Combat Aircraft (AMCA) and other indigenous platforms.
- A foundation was also laid for the Naval Systems Manufacturing Facility at T Sirasapalli, Anakapalli, for advanced underwater weapons and naval combat systems.
- Grounding ceremonies were held for a Defence Energetics Facility and an Ammunition & Electric Fuses Plant at Madakasira.
- A consortium of eight drone companies was announced to establish a Drone City at Kurnool.
- The Minister placed the announcements against a sharp rise in defence output: production at about ₹1.54 lakh crore (up from ₹46,000 crore in 2014) and exports near ₹40,000 crore (from roughly ₹600 crore a decade ago).
Background & context
The Advanced Medium Combat Aircraft is India's programme to design and build a twin-engine, fifth-generation stealth fighter. It is the apex of a lineage of indigenous fixed-wing combat-aircraft development that runs through the Light Combat Aircraft (LCA) Tejas family. Where the single-engine Tejas is a 4.5-generation jet, the AMCA is conceived a full generation beyond it — built around low radar observability (stealth), an internal weapons bay, supercruise potential and advanced sensor fusion. It is the aircraft meant to sit at the top of the future Indian Air Force combat fleet, slotting above the Tejas Mk1A and the planned Tejas Mk2.
The design authority for the AMCA is the Aeronautical Development Agency (ADA), the same Bengaluru-based agency that steered the Tejas through development. ADA functions under the Department of Defence Research & Development and works closely with the Defence Research and Development Organisation (DRDO); for that reason ADA is commonly described as a DRDO-affiliated body, with the release calling the new testing centre an ADA facility that is a DRDO affiliate. The manufacturing model is the notable shift: rather than handing the build solely to the public-sector Hindustan Aeronautics Limited (HAL), the programme has moved toward a competitive model in which private industry can partner on production — part of a broader push to widen the defence-industrial base beyond the traditional public-sector monopoly.
The Cabinet Committee on Security cleared the AMCA programme's full-scale engineering development, and the project has a reported overall outlay in the order of ₹15,000 crore for the development phase. The new Core Integration & Flight Testing Centre — costing about ₹2,000 crore — is the physical infrastructure where the airframe, engine, avionics and weapon systems are brought together (integration) and then put through the flight-test campaign that any new fighter must complete before induction. Puttaparthi's selection extends India's aerospace-testing footprint and anchors a defence-manufacturing corridor in Andhra Pradesh, complementing the established design-and-build cluster around Bengaluru.
The other projects announced the same day round out a deliberately spread industrial map. The Naval Systems Manufacturing Facility at Anakapalli is a ₹480 crore project of Bharat Dynamics Limited (BDL), the defence public-sector missile and underwater-weapons maker, focused on autonomous underwater vehicles, underwater counter-measures and next-generation torpedoes. The Defence Energetics Facility is a ₹1,500 crore project of Agneyastra Energetics Limited, described as a subsidiary of the private major Bharat Forge, while the Ammunition & Electric Fuse Plant is a ₹1,200 crore project of HFCL Limited — both at Madakasira. The eight-firm Drone City consortium at Kurnool reflects the rapid build-out of an indigenous unmanned-systems ecosystem. Taken together, the cluster is a microcosm of the present defence-manufacturing strategy: a mix of public-sector undertakings (ADA, BDL) and private industry (Bharat Forge's energetics arm, HFCL, the drone consortium), each anchored to a different segment of the value chain — airframe integration, underwater weapons, propellants and explosives, ammunition, and unmanned systems — and concentrated geographically so that suppliers, skills and testing infrastructure reinforce one another.
It helps to be clear on what the word "generation" carries for fighter aircraft, since the distinction is exactly what examiners probe. Fifth-generation jets are defined less by raw speed than by a bundle of features: a stealthy, low-observable airframe shape and radar-absorbent treatment; the carriage of weapons in an internal bay so the aircraft stays clean to radar; highly integrated sensor fusion that blends radar, infrared and electronic inputs into a single picture for the pilot; and, on the more capable designs, the ability to cruise at supersonic speed without afterburners (supercruise). A 4.5-generation jet such as the Tejas has modern avionics and an active electronically scanned array radar but lacks the stealth airframe and internal weapons carriage that define the next tier. The AMCA is being designed to cross that line, which is why it is a far heavier engineering undertaking than the Tejas was — and why dedicated integration and flight-test infrastructure is treated as programme-critical rather than incidental.
For Prelims
- Full name: AMCA = Advanced Medium Combat Aircraft — India's fifth-generation stealth multirole fighter programme.
- Generation & class: fifth-generation, twin-engine, medium-weight stealth fighter — a generation above the 4.5-gen Tejas.
- Design authority: Aeronautical Development Agency (ADA), a DRDO-affiliated body under the Department of Defence R&D; the same agency behind the Tejas LCA.
- Manufacture: through a competitive model open to private industry alongside HAL — not a single public-sector build.
- Programme outlay: development phase of the order of ~₹15,000 crore; the new Core Integration & Flight Testing Centre ~₹2,000 crore.
- New facility: Core Integration & Flight Testing Centre at Puttaparthi, Sri Satya Sai district, Andhra Pradesh — an ADA facility.
- Naval Systems Manufacturing Facility: Anakapalli (T Sirasapalli), Andhra Pradesh · ₹480 cr · Bharat Dynamics Limited · autonomous underwater vehicles, counter-measures, next-gen torpedoes.
- Energetics & ammunition: Defence Energetics Facility (Agneyastra Energetics, a Bharat Forge subsidiary) ₹1,500 cr + Ammunition & Electric Fuse Plant (HFCL) ₹1,200 cr, both at Madakasira.
- Drone City: consortium of eight drone firms at Kurnool, Andhra Pradesh.
- Sector data (as stated): defence production ~₹1.54 lakh crore (from ₹46,000 cr in 2014); exports ~₹40,000 crore (from ~₹600 cr a decade ago).
The Indian indigenous fixed-wing combat fleet — the full set to keep straight: HAL Tejas Mk1 / Mk1A (single-engine, in-service 4.5-gen LCA) → planned Tejas Mk2 / Medium Weight Fighter (a larger single-engine evolution still in development) → AMCA (twin-engine, fifth-generation stealth, the apex). The associated naval fighter effort is the TEDBF (Twin-Engine Deck-Based Fighter) for aircraft carriers. Keeping this ladder in order defends against any "arrange in order of generation" or "match the platform" question.
Why it matters
A fifth-generation fighter is among the most demanding systems any country can attempt to build, and only a handful of nations operate one. The AMCA, if it matures, would place India in that very small group and reduce dependence on imported front-line jets — directly addressing the long-standing problem of India being among the world's largest arms importers. The flight-test centre is a quiet but essential piece: a new fighter lives or dies in the years of integration and flight testing between first flight and induction, and dedicated infrastructure for that phase removes a real bottleneck. The decision to open AMCA production to private players, and to seed a clustered defence-manufacturing corridor in Andhra Pradesh, speaks to the wider goal of indigenisation — building domestic capability across airframes, underwater weapons, energetics, ammunition and drones rather than buying these capacities off the shelf. The production and export figures cited frame the policy claim: a defence-industrial base that has grown several-fold over a decade and is now exporting at scale.
There is also a regional-development dimension. By siting the integration-and-test centre, the naval-systems plant, the energetics and ammunition units and the Drone City in Andhra Pradesh, the announcement extends India's defence-manufacturing geography beyond its established nodes and ties aerospace investment to a state actively courting it. For the Air Force, the strategic logic is the steady replacement of an ageing combat fleet — squadrons that have for years drawn on imported and licence-built types — with a domestically controlled top-tier platform, insulating front-line capability from the supply, spares and upgrade risks that come with depending on foreign original-equipment manufacturers. The same self-reliance argument runs through the naval and unmanned-systems projects: underwater weapons and drones are precisely the categories where supply-chain control and rapid iteration matter most, and where building at home converts a procurement dependency into an industrial asset.
